Abstract
Leštiace prostriedky sú určené na leštenie výrobkov z prírodného a konglomerovaného mramoru. Leštiace prostriedky, ktoré sú predmetom vynálezu, obsahujú 80 až 90 hmotnostných dielov kyseliny šťavelovej a 10 až 20 hmotnostných dielov pojivá. Pojivom je fenolformaldehydová živica, ktorá vzniká zmiešaním fenolového novolaku a hexametyléntetramínu pri zvýšenej teplote.Polishing agents are intended for polishing products made of natural and conglomerated marble. The polishing agents which are the subject of the invention contain 80 to 90 parts by weight of oxalic acid and 10 to 20 parts by weight of binder. The binder is phenol formaldehyde resin, which is created by mixing phenol novolak and hexamethylene tetramine at elevated temperature.
Description
Vynález sa týká leštenia výrobkov z prírodného a konglomerovaného mramoru pomocou viazaných leštiacich prostriedkov róznych tvarov (kotúče, segmenty).The invention relates to the polishing of natural and conglomerated marble products by means of bonded polishing means of various shapes (discs, segments).
Na leštenie výrobkov z prírodného a konglomerovaného mramoru sa používajú rožne leštiace prostriedky ako například kyselina šťavelová a jej soli, kysličník cíničitý, kysličník hlinitý a Iné. Leštenie sa prevádza takým spósobom, že na leštenú plochu sa nanesie příslušný leštiaci prostriedok v sypkom stave, ovlhčí sa vodou a pomocou íilcového kotúča sa dosiahne vyleštenie. Takýto spósob leštenia mramorových výrobkov je zdlhavý a nie je možné ho použiť na kontinuálnych leštiacich linkách.For polishing natural and conglomerated marble products, various polishing agents such as oxalic acid and its salts, tin dioxide, alumina and others are used. The polishing is carried out in such a way that the respective polishing agent is applied to the polished surface in a loose state, moistened with water and polishing is achieved by means of a roll disc. Such a method of polishing marble products is lengthy and cannot be used on continuous polishing lines.
Tieto nedostatky odstraňuje predmet vynálezu, ktorým sú viazané leštiace prostriedky na leštenie výrobkov z prírodného a konglomerovaného mramoru. Viazaný leštiaci prostriedok podta vynálezu obsahuje ůčinnú leštiacu zložku, ktorou je kyselina šťavelová a pojivo, ktoré tvoří fenolformaldehydová živica. Fenolformaldehydová živica vzniká zmiešaním fenolového novolaku a hexametyléntetramínu v predpísanom pomere pri zvýšenej teplote (60 až 80 °CJ. V praxi sa móžu používat bakelitové tmely BT 1, BT 2 s obsahom 8 až 10 °/o-nom hexametyléntetramínu. Popísané viazané leštiace prostriedky obsahujú 80 až 90 hmotnostných dielov kyseliny šťavelovej a 10 až 20 hmotnostných dielov uvedeného pojivá.These drawbacks are overcome by the subject matter of the invention, which binds polishing means for polishing natural and conglomerated marble products. The bound polishing composition according to the invention comprises an active polishing component which is oxalic acid and a binder which forms a phenol-formaldehyde resin. The phenol-formaldehyde resin is formed by mixing the phenolic novolak and hexamethylenetetramine at a prescribed ratio at elevated temperature (60-80 ° C. In practice, BT 1, BT 2 bakelite cements containing 8-10% hexamethylenetetramine can be used. 80 to 90 parts by weight of oxalic acid and 10 to 20 parts by weight of said binder.
Příklad zloženia viazaných leštiacich segmentov pre leštenie prírodného a konglomerovaného mramoru na kontinuálnej brúsiacej a leštiacej linke „Breton“ je nasledovný:An example of the composition of bonded polishing segments for polishing natural and conglomerated marble on a continuous "Breton" grinding and polishing line is as follows:
kyselina šťavelová 0,45 kgoxalic acid 0,45 kg
BT 1 alebo BT 2 0,05 kg lieh (denaturovaný) 10 mlBT 1 or BT 2 0.05 kg alcohol (denatured) 10 ml
Navážené množstvo kyseliny šťavelovej sa premieša s liehom a přidá sa navážené množstvo bakelitového tmelu. Táto zmes sa znovu premieša a vytvaruje sa na žiadaný tvar lisováním. Takto vytvarované leštiace prostriedky sa vytvrdzujú pri teplote 60 až 80 °C dve až štyri hodiny.Mix the weighed amount of oxalic acid with alcohol and add the weighed amount of bakelite putty. This mixture is again mixed and formed to the desired shape by compression. The polishing compositions thus shaped are cured at 60-80 ° C for two to four hours.
Povrch mramorových výrobkov, ktorý chceme popísanými leštiacimi prostriedkami leštit, musí byť vybrúsený brusivom s hrúbkou zrna č. M-22 až M-15.The surface of the marble products to be polished by the polishing agents described above must be ground with abrasive with grain thickness no. M-22 to M-15.
Viazané leštiace prostriedky podta vynálezu je možné aplikovat na leštenie ostatných materiálov, ktoré sa dajú leštit kyselinou šťavelovou.The bound polishing compositions of the present invention can be applied to polishing other materials that can be polished with oxalic acid.
